ATOWIIZER.4

SPECIFICATION forming part of Letters Patent No.' 692,722, dated February 4, 1902. Application tiled May l1l 1900. Renewed December 24, 1901. Serial No= 87,049. (No model.)

To a/ZZ whom t may concern,.-

Beit known that I, CYRUs J AY SELTZER, of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Atomizers and Nebulizers, of which the following is a specification.

Myinvention relates to atomizers and nebulizers; and it consists in the parts and improve-- ments hereinafter described and claimed.

In the accompanying drawings, forming part of this specification, Figure l'is acentral vertical sectional view of my combined atomizer and nebulizer. Fig. 2 is a sectional View taken on line of Fig. 1. Fig. 3 illustrates two modifications of the airand liquid.

7 is a block secured to the portion 6 of theV cap and provided with two passages 8 and 9. The passage 8 communicates at one end with the interior ot' receptacle 3 and at the other end with an aperture 10 through the diaphragm 6. The passage 9 is connected at one end to a nebulizing-tube 27 within receptacle 3 and at the otherv end with a passage 11 in diaphragm 6. Y l

12 is a recess in the diaphragm 6 for the reception of a three-way cock or valve 16.

The valve 16 is provided with a passage 17, arranged in communication with an aperture 18 through the Wall of said val-ve. The outer end of valve 16 is adapted t0l be placed in communication With any suitable source of fluid-pressure supply.

14 is the usual inner or liquid atomizertube, extending through an aperture 13 in the diaphragm 6 and through the outer atomizertube 15.

19 is any well-known form of detachable atomizing-tip secured at the outer ends of the tubes 14 and 15.

communication with the nebulizing-tube 27 through passages 11 and 9. In this position ofthe valve the fluid under pressure entering passage 17 of said valve will nebulize the Iinid 4, and` the nebulized Huid will issue by Way of passages 8 and l0 and outer tube 15.

In using my device for atomizing the liquid A 2 the cap 19 is properly attached and the valve .16 is turned, 4as shown in Fig. 2, with its ap.

erture 18 in communication with the passage v1i 3 through the diaphragm 6. In this position of the valve the fluid under pressure entering passage 17 of said valve will issue into the passage 13.` A portion of the Huid will pass downward through passage 13 and exert sufficient pressure on the liquid 2 to force it up through the tube 14. Another portion of the fluid under pressure will pass upward from passage13 through the outer tube 15 and escape through the atomizer-tip 19. This portion of the iiuid will impinge in the usual manner on the liquid rising through the tube 14 into the tip 19 and cause said liquid to issue from the tip in a jet of spray.

Fig. 3 illustrates two modifications in which the nebulizer-tube is formed ot'- an ordinary commercial rod or bar 20 of suitable material. Referring first to the construction shown at the left in Fig. 3, two intersecting passages 2l are drilled` or otherwise formed Vthrough the rod 20, the peripheral openings of these two passages constituting four jet-passages. Four passages 22 are then formed inthe rod, the four passages 22 extending from the bottom of the rod into communication with passages 21 at points adjacent to the' periphery of the rod, these passages 22 thus constituting four liquid-passages, one for each jet-passage. I then form the air or other fluid passage 23 from the top of the rod to the point of intersection of the passages 21 21. y While I have shown only two intersecting passages 21, and therefore four Ajet-passages, it is obvious that a greater number could be employed, if found desirable, or that a sin glefpassage 21 could be employed.

IOO

In the construction shown at the right in Fig. 3 a passage 24 is rst formed partly through-the rod 20. The liquid-passage 25 and air-passage 26 are then formed,extending, respectively, from the bottom and the top of rod into communication with the passage 24, as shown. By thus constructing my nebulizer-tube containing the air, liquid, and jet passages of a single integral piece of straight rod it can be made exceedingly small to adapt it for use with Very small bott-les, andthe cost of manufacturing the tube is greatly reduced.

As shown,the air-passage 2G has been drilled or otherwise formed entirely through the rod 2O and its lower end then closed by a plug 26 of suitable material. In this modication a tube could be employed instead of the rod, in which case the bore of the tube would constitute the air-passage and would be closed at the bottom by a plug, as 26.

Having thus described my invention, I

i claim as new and desire to secure by Letters with the passage 9, a valve provided with a longitudinal passage and a lateral aperture communicating therewith, said Valve being so located in the recess 12 that it can be adj usted.to place said lateral aperture in communication with either the recess 11 or the passage 13, an outer atomizer-tube carried by said cap, an inner atomizer-tube passing through said outer tube and passage 13 and extending into the outer receptacle, and a detachable atomizer-tip carried at the outer ends of the atomizer-tubes, substantially as shown and described.

In testimony whereof I hereunto set my hand, this 7th day of May, 1900, in the presence of two attesting Witnesses.

CYRUS JAY SEL'IZER.
